I have a problem with a microphone TLM 193 S/N 01178 And this problem seem to come from IC2 on the electronic circuit. After I had talk to the distributor Neumann in Canada (Sennheiser Canada ) They have tell me that they donít have any schematic advalable. And that IC2 and IC1 are not advalable.
Only the complete electronic PCB assemble his advalable at the price of $735.00 ca. I am very desapointed that the IC2 is not advalable and it is unacceptable to change the complete electronic circuit at the coast of $735.00ca.
